F115Prenatal diagnosis and clinical management of fetal hydro(metro)colpos: report of 3 cases

Background Hydrometrocolpos represents the dilatation of the vagina and uterus due to obstruction of the genital tract, leading to accumulation of secretions. We report on 3 female fetuses with prenatally diagnosed hydro(metro)colpos. Gestational age ranged from 28 to 35 week's. In the first case, hydrometrocolpos was associated with postaxial hexadactyly of both upper extremities, strongly indicating McKusick Kaufman syndrome. In the second case, malformation of the urogenital sinus included anorectal and vaginal atresia with rectovaginal and urethrovaginal fistula. Furthermore, vertebral segmentation anomalies, horseshoe kidney and ventricular septal defect were detected, creating an overlap between VACTERL and MURCS association. In the third case, hydrometrocoplos secondary to cloacal anomaly with anal atresia and bilateral hydronephrosis were observed. All 3 newborns underwent surgical correction, 2 of them survived. Conclusion The presence of hydro(metro)colpos warrants a systematically evaluation of fetal and neonatal anatomy to rule out a large variety of possibly associated malformations or syndromes.
